tools: remove tmem code and commands
Remove all tmem related code in libxc.
Leave some stubs in libxl in case anyone has linked to those functions
before the removal.
Remove all tmem related commands in xl, all tmem related code in other
utilities we ship.

- Note that live migration complicates the save/restore format in
- multiple ways: Though saving/migration can only occur when all
- tmem pools belonging to the domain-being-saved are frozen and
- this ensures that new pools can't be created or existing pools
- grown (in number of pages), it is possible during a live migration
- that pools may be destroyed and pages invalidated while the migration
- is in process. As a result, (1) it is not safe to pre-specify counts
- for these values precisely, but only as a "max", and (2) a "invalidation"
- list (of pools, objects, pages) must be appended when the domain is truly
- suspended.
